Requirements to install in an existing Red Hat OpenShift cluster

Review the following considerations if you plan on installing Maximo® Application Suite in an existing Red Hat® OpenShift® cluster.

Cluster administrator rights

Maximo Application Suite requires global/cluster administrator rights to install. Maximo Application Suite is a cross namespace (cluster wide) application and requires cluster-admin access to create and update custom resource definitions/namespaces, get cluster information for automation and OpenShift Lifecycle Management related tasks.

The cluster-admin role is required by Maximo Application Suite and used to create and manage resources needed by Maximo Application Suite. However, no global changes will be applied by Maximo Application Suite. Cluster administrators are required to install Operators by default. It is not recommended to allow non-cluster administrators to install Operators.

Cluster-wide settings

Maximo Application Suite installations or upgrades will not change any cluster-wide settings other than the resources created by Maximo Application Suite itself. Maximo Application Suite requires IBM® Certificate Manager 1.15 or later to install Maximo Application Suite in the cluster. If IBM Certificate Manager is a shared dependency between the cluster, upgrading it might affect other applications in the cluster.
